Inflatable sex dolls are interesting, in that anyone who tries to use one for its stated purpose clearly doesn’t understand the situation. I fully believe that even the people who make inflatable sex dolls do not expect them to be inflated and used for sex, and would be horrified to think that anyone attempted it. They are gag gifts, and nothing more. If they actually intended for any human to attempt to copulate with one, they’d make some attempt to make them less horrifying to look at, touch, or think about. It would be an unsuccessful attempt, but at least they would try.
